NO POWER TO CRANK AND CAM SENSOR

1996 Chevrolet S-10 • 67,000 miles

When tried to start the vehicle I got no spark after testing all sensors and coil packs I found no power to crank and cam sensors tested pcm plug found power to some wires tested ground at plug found other wires were ground. Which wires should be power and which should be ground?

Im sorry its a 2.2 4 cyl no distributer only coil packs and they all checked out good, all new wires and plugs got power to pcm plug but no power to cam and crank sensor unless I jump the power from the battery buit still get no fire
